r-ViTiocVzZlz'viom it may'cof/'tc67%.*V Belitknown/that I,' -STEPHEN D. vI-IAi'rroG, 'afeitizen'of the UnitedStates, anda resident Vl of thef'city 'of St. Louisfaiid State' of'Misv'souri',='have invented Vnewaiid luseful Improvements in. yElbow Fittings 4for Engines,

*of which the following isa specification; 'fV

This invention relates toV-an' elbow fitting forengines,-"i`nre particularly tothe characportionof-internalcombustion engines. The present type'offelbows in common use are employed as a connectingmem'ber between' i the cylinder head of the internal combustion engine and radiator, connecting the Acyl- -inder head with the radiator through which the water cooling medium has passage. Y

It is a well known fact that L-Vvery useful devices'could be economically employed and z operated-by the'engine were a convenient place provided on the engine for their attachinent if it were not, as is now the case,

Vdrawing in which:V K

Fig. l is a side elevation illustrating the of having to resort to the expense andV difficulty in forming special bracketsand` drill-` ing and'. tapping specialholes in different places aboutk the, engine for these attachable parts. Y Y I The object therefore of the `present invention isVto provide a place or location very conveniently and inexpensively sov that suitable and useful devices may "readilyV be attached and detached without practically any loss of'time or any appreciableexpense.

To siichends this 'invention' consists in.

constructing an elbow in such a novel way whereby provisioii'is made enabling the elbow to support a shaft or stud, or to be einployed as a'hanger support for devices attachable thereto, by forming projecting portions or prongs integral with .the body of the manner in which the elbow is attached. j

Fig. Q'is a front viewjo'f the elbowllooking in the direction of the arrow Fig. l.

In the drawing, l0 designates the Vbody of the elbow having a flanged end ll, through which holes l2 are drilled to receive boltsl '(shown in dotted outline), two of-which are used to screw into holes, tapped in a corre- -spondiiig flanged eiid'of the upper end ofv speifcaia @fata-fs staf .rai-haagsefinita?. i

the cylinder head 14; (shownin dotted outf line 515) and to? which' the elbow VlOisV fcl'amped. i if LThe end "16 of the elbow, opposite the i Adang-ed end 1l',-'isV forinedfwitha beading or VV L i V 'ridgel' ofjfveryfnarrowwidth andl'slightlyf Y .l'argerV in `diameter than the 'diameter ,of` lthe j bodyr` of""'theV elbow'ilO. v@ver fthe'e'nd ter of elbows as used on thecyl-inder vhead .16 shfourt llength off-hose 18 iV`(`shownf in dotted outline) 'is pressed landjintywhich the beading 17 isajdapte'dto makejanfimpres-f A Y sion forming a seat to prevent leakage when v clamped by a metal band (not shown) positioned on theouter surface of the hoseconnection 18. The internal portion of the el- V bow l0 is cored through its entirelength, as

indicated at j y Theforegoing description'is of the elbow l0 as it is in commonuse Aand for which no claim for novelty or invention ismadeexcept inv combination with and as a `unitary structure as heiein next described.VV Project- Ving portions orprongs 2O are formedor` cast Vintegiallyfwith the b'odylOAofjthe el- Y bow, providinganv additional-capacity to the V.elbow 1Q', enhancing its usefulness, in that Vthe' projecting portions can be drilled or tapped at 2l to supporta Shaft 22 (shownlin sorv .85 'V dotted outline)v or the projecting portion f V Vmay otherwisebef-converted into ahanger e `support for any suitable device attachable n thereto. The *Y advantage, convenience, `and Y economy of having a locationto make at- V tachable connections with operable vparts oftheengine which the positionA of the elbow affordsV when provided with the means for Vacomplishing this endcannot be overstated.

In the manufacturing of my improved el-V bow the first requirement is to have'a patlternfmade of -the requisite size. and shape` from which .castings are made in duv V .plicate.` The castings are then machined on theV coniiectingface of the flanged end l1 of. the 'body l0; holesV are drilledin the flanged um j end 1l to mate with the holes'as drilled and tappedin the flanged end lli of the cylinder head 15, fandholes'Qla-re then drilledVV and tapped, as the'case :may require, in the' pose of supporting a shaft or stud or other V V suitable parts as hereinbefoie explained.

It is obvious from the foregoing description that this constructionV of elbow fulfils the purpose-for which itis intended and it is to be understood that minor changes may be head of an internal 'combustion engine with the radiator, having projecting portions or prongs adapted to form a support for parts attachable thereto..

2. As a new `article of manufacture, a conne'cting membefr'for connecting the flanged end of a cylinder head of an internal conibustion engine with the radiator, having projecting portions or prongs adapted to form asupport for parts attacl'lable thereto, and operable by thev engine.

3. As a new article of manufacture, an elbow fitting for the flanged end of the cylinder head of an internal combustion en` gine, forming a connection with the radiator, `said elbow being provided with projecting portions adapted to forni a support for parts attached thereto.

t. As a new 'article of manufacture an elbow fitting employed as the connecting member between the flanged end of the cylinder head ofthe internal combustion engine and the connecting end .of the radiator and positioned therebetween,.projecting portions on said elbow adapted to forni a support 'or hanger for parts attachable thereto and operable by said en ine.
